NOTES

1. Amino acid number is standardized to the Arabidopsis thaliana sequence

2. The letters indicate the level of resistance conferred by the mutation

• S = Susceptible biotype
• r = Moderate resistance (< 10-fold relative to sensitive biotype)
• R = High Resistance (> 10-fold)
• ND = Not Determined

It should be noted that these classifications are generalizations.

3. The year that the mutation was first reported: see details for reference.

HERBICIDE FAMILY ABBREVIATIONS

IMI = Imidazolinones
PTB = Pyrimidinylthiobenzoates
SCT = Sulfonylaminocarbonyltriazolinone
SU = Sulfonylureas
TP = Triazolopyrimidines
